While Nest hasn’t fixed the problem yet, all Protect smoke detectors that have already been sold were automatically updated to deactivate the feature in April if they were connected to the internet. Nest originally said that addressing the issue and reactivating the feature could take two to three months, including approval from regulatory agencies in the US, Canada, and UK ahead of an update. Even without the Wave feature, the Nest Protect offers smart features like voice-activation, the ability to communicate with a Nest Thermostat to enable an auto-away feature, and phone alerts for smoke or carbon monoxide even if you’re away from home.
